Laser projector for home cinema

The BenQ LH650 is a DLP laser projector built for home theatre use. It produces a native 1080p image at 4000 lumens brightness with a 3,000,000:1 contrast ratio. The laser light source removes the need for lamp replacements over extended viewing sessions.

Suited for bright-room viewing and simple setup

This model serves viewers who want a large 16:9 picture in rooms with ambient light and who value the low maintenance of a laser engine. It is not suited for buyers who require motorised lens shift or keystone correction beyond ±30 degrees vertical and horizontal.

Throw ratio 1.15 to 1.5 determines placement

The lens offers a throw ratio between 1.15 and 1.5 with a focal length of 16.88 to 21.88 mm and an aperture of f/2.59 to f/2.87. This range fixes how far back the unit must sit for a given screen width, making it the key specification for room planning.

Questions about this item

What bandwidth does the HDMI connection support for 1080p and 4K signals?

The projector accepts 1080p up to 120 Hz vertical refresh and 4K input, though the native panel is 1920×1080 so 4K is downscaled.

What throw ratio and lens shift range does the LH650 offer for placement flexibility?

Throw ratio is 1.15~1.5 with a 1.3× zoom lens; vertical and horizontal keystone each correct ±30 degrees for off-centre mounting.

How do you enable the USB-C DisplayPort Alt Mode with 5 V/1 A power delivery?

Connect a USB-C source that supports DisplayPort Alt Mode to the single USB-C port; the projector negotiates video and supplies up to 5 V/1 A automatically.
